<div><span style="font-size: medium">&nbsp;</span></div>
<div><span style="font-size: medium">最近IK正在做关于地形建模的工作。其中一个工作阶段就是把一些山排列成一行。每座山都有各不相同的标号和高度。为了遵从一些设计上的要求，每座山都设置了一个关键数字，要求对于每座山，比它高且排列在它前面的其它山的数目必须少于它的关键数字。</span></div>
<div><span style="font-size: medium">&nbsp;显然满足要求的排列会有很多个。对于每一个可能的排列，IK生成一个对应的标号序列和等高线序列。标号序列就是按顺序写下每座山的标号。等高线序列就是按顺序写下它们的高度。例如有两座山，这两座山的一个合法排列的第一座山的标号和高度为1和3，而第二座山的标号和高度分别为2和4，那么这个排列的标号序列就是1 2，而等高线序列就是3 4.</span></div>
<div><span style="font-size: medium">&nbsp;现在问题就是，给出所有山的信息，IK希望知道一共有多少种不同的符合条件的标号序列和等高线序列。</span></div>
<div><span style="font-size: medium">&nbsp;</span></div></p><hr/><h3>输入格式</h3><p><div><span style="font-size: medium">输入第一行给出山的个数N。接下来N行每行有两个整数，按照标号从1到N的顺序分别给出一座山的高度和关键数。</span></div>
<div><span style="font-size: medium">&nbsp;</span></div></p><hr/><h3>输出格式</h3><p><div>&nbsp;</div>
<div><span style="font-size: medium">输出两个用空格分隔开的数，第一个数是不同的标号序列的个数，第二个数是不同的等高线序列的个数。这两个答案都应该对2011取模，即输出两个答案除以2011取余数的结果</span></div>
<div><span style="font-size: medium">&nbsp;</span></div></p><hr/><h3>样例输入</h3><pre>
2
1 2
2 2
 
</pre><hr/><h3>样例输出</h3><pre>
2 2
</pre><hr/><h3>提示</h3><p><p>对于所有的数据，有1&lt;=N&lt;=1000，所有的数字都是不大于109的正整数。</p></p><hr/><h3>题目来源</h3><p>没有写明来源</p>
